[FIB]: Add netns to fib_rules_ops.

2008-01-28T23:08:13+00:00

The backward link from FIB rules operations to the network namespace
will allow to simplify the API a bit.

[NETNS]: Pass fib_rules_ops into default_pref method.

2008-01-28T23:01:22+00:00

fib_rules_ops contains operations and the list of configured rules. ops will
become per/namespace soon, so we need them to be known in the default_pref
callback.

[NETNS]: Add netns parameter to fib_rules_(un)register.

2008-01-28T23:01:21+00:00

The patch extends the different fib rules API in order to pass the
network namespace pointer. That will allow to access the different
tables from a namespace relative object. As usual, the pointer to the
init_net variable is passed as parameter so we don't break the
network.

[INET]: Small possible memory leak in FIB rules

2007-11-11T06:12:03+00:00

This patch fixes a small memory leak. Default fib rules can be deleted by
the user if the rule does not carry FIB_RULE_PERMANENT flag, f.e. by
	ip rule flush

Such a rule will not be freed as the ref-counter has 2 on start and becomes
clearly unreachable after removal.

[IPV4/IPV6/DECNET]: Small cleanup for fib rules.

2007-10-10T23:51:22+00:00

This patch slightly cleanups FIB rules framework. rules_list as a pointer
on struct fib_rules_ops is useless. It is always assigned with a static
per/subsystem list in IPv4, IPv6 and DecNet.

[NET] fib_rules: Flush route cache after rule modifications

2007-04-26T05:28:18+00:00

The results of FIB rules lookups are cached in the routing cache
except for IPv6 as no such cache exists. So far, it was the
responsibility of the user to flush the cache after modifying any
rules. This lead to many false bug reports due to misunderstanding
of this concept.

This patch automatically flushes the route cache after inserting
or deleting a rule.

Thanks to Muli Ben-Yehuda  for catching a bug
in the previous patch.
